Product Description
Kenko DG Teleplus Extension Tube Set
Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.
The DG extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.
The KENKO DG AUTO EXTENSION TUBE SET contains three tubes of different length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any combination to obtain the desired magnification. Kenko also makes a DG UNITUBE 12 mm or 25 mm which can be purchased individually.
Kenko's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Canon, Nikon, and Minolta lenses given there is enough light to activate the cameras AF system properly.

 Turn most or all of your lenses into macro lenses August 18, 2010
J. S. McRoberts (Seattle, WA)
Kenko extension tubes were recommended to me by a professional photographer, and he was right on the money. They're much cheaper than the Canon ones, as well as more flexible (three sizes vs. two). I recently attended a (highly recommended) photo workshop with Bryan Peterson (author of Understanding Exposure and other books), and needed a macro lens. No problem--all my lenses are now macro lenses with these tubes. I got some great macro shots and I'm excited to use these tubes as I continue to apply the new techniques I've learned.
The tubes themselves are very solid and well-made. They have a nice coating and hold my precious "L" lenses securely. The documentation provided is minimal but sufficient (always attach the tubes to the camera, then the lens to the tubes to make sure the lens is registered properly by the camera). I've used them on both my Canon 40D and 5D Mark II with great results.
For those with EF-S lenses (white mounting alignment markings): no worries, these are the updated DGs model despite the outdated picture you might see on this page, and they work fine.
Pricey, but really the best option out there. July 14, 2010

Extension tubes are known to some as "the poor mans macro" - basically a (cheap-ish) way to get macro capability out of your existing lenses. If you've ever looked into a macro lens, you've seen just how much they cost (not cheap! Especially for a good one). If you just want to try it out before plunking down the cash, the Kenko tubes are the way to go.
Basically these are hollow tubes that fit between the lens and your camera and decrease the minimum focusing distance of your lens.
Lenses have a "minimum focusing distance" - a set amount that you have to be away from the subject for it to focus. If you've used a telephoto, you've probably seen how you need to be about 3 feet back for it to focus.. these greatly decrease that distance.
The set comes with 3 tubes (different sizes). Use 1, 2 or 3 at a time (the larger size (or more used) the closer you can get).
One big difference between these and a dedicated macro are that these don't focus to infinity. Macro can get VERY CLOSE or VERY FAR from the subject and focus - sort of like an "all around super lens" - the tubes let you get VERY CLOSE, but won't let you focus on objects far away (you need to take the tubes off to do that).
Now you've probably seen cheap tubes on some auction site - these cost about 5% of what the Kenko tubes cost, so why get these? the key here is that these have electrical contacts - that means you can adjust the aperture/autofocus with these tubes (whereas the others you can't - you need to do weird tricks to change the aperture on the lens). This change, while not seeming like much, makes a BIG difference.
With something like a 50mm 1.8 lens, you can literally focus within about an inch or two of the lens - this can sometimes be tricky because: (A) you'll create shadows and need to light them somehow and (B) subjects like bugs won't wait around for you. That's where this option has problems. You can get around issue (A) by using an off-camera flash (check out the "Rayflash" for your flash/camera - works great for these macro shots!) - for (B), you're kinda out of luck. If you're trying to get the crazy insect photos with live insects, you'll have a hard time.
One thing to watch out for is putting too many tubes on your lens. Wider-angle lenses will take less tubes than telephotos - if you add too many (adding all tubes to a 30mm lens, for example, you'll decrease the focusing distance so far that it's actually inside of the lens). So try it out and see what works for you. I've found the 50mm 1.8 Canon works best with the tubes (all 3 of them) and you can get some INCREDIBLE shots -- just learn the limitations and you'll be very happy. If you decide you want more, look into a nice dedicated macro lens!

As a person who recently in December switched from a point and shoot to a DSLR i was at a lost for a good macro solution. Do not get me wrong there are many macro lenses and options out there but I am currently a college student so money can be a little low at the best of times. So when I found these tubes I was thrilled! After some research into them I decided to make the purchase and I have been very pleased with the results!!! This and the 50 mm 1.8 lens by canon go very well with each other, as well with the 55-200mm EF-S lens. They can produce very good results with little effort. So if you are looking for a cheap way to pull off some professional looking macro i would highly recommend these tubes!!

Let me start off by saying that I typically ignore 5 star reviews because I find them unhelpful. But in all honesty I would be remiss if I left this product less than full marks. For me the question was whether to buy the Cannon 100mm macro lens or these tubes. I decided to go for the tubes and spend the remaining ~$350 buying a tripod, a ball head, a camera bag, and an infrared filter. These tubes are wonderfully useful. I have tried them on all of my lenses (canon 18-55mm, 50mm f/1.4, 28-135mm, 55-250mm) and they have worked well on all of them and in every combination possible. Best of all, I have found that if you put some or all of these tubes on the 55-250mm lens (cheap by all standards) you end up with a brilliantly useful macro lens with a relatively long working range. I would recommend these tubes to anyone even if they are not interested in macro photography. These tubes, more than any other toy in my camera bag, have significantly increased my range of creativity.
Simply a must have.
Perfect for bringing those little things closer. May 26, 2010
Designed to work (On the edge.)
This may not be glass but well worth the money. I used these with the Sigma 70/200mm f/2.8 with the Sigma ring flash attached. With all 3 attached the flash is almost level with the subject, now that's close ;-) Great build quality and a permanent addition to my bag. I would recommend these.
